Description

本発明は、椅子柱に置かれた基部支持体と、座部支持部材と、背凭れ支持部材とを有するオフィス椅子の座部と背凭れを相関動作させるシンクロ機構に関する。   The present invention relates to a synchronization mechanism that correlates a seat back and a backrest of an office chair having a base support, a seat support member, and a backrest support member placed on a chair pillar.

「シンクロ機構」とは、オフィス椅子の座部の構成におけるアセンブリを意味するもので、座部と背凭れを所定の関連動作させる運動学的な連結構成をいう。一般に、布や革を張った椅子の座部は、オフィス椅子の座部支持部材上に載置されている。背凭れ支持部材は、実際にはシンクロ機構から後方に伸延し、垂直な片持ち梁にオフィス椅子の背凭れを支持している。座部支持部材と背凭れ支持部材は、通常、弾力的に連結され、例えば、背凭れに椅子のユーザーがもたれることによって起こされる背凭れの後傾が、座部の後端部を下方に誘導するようになっている。   The “synchronizing mechanism” means an assembly in the configuration of the seat portion of the office chair, and refers to a kinematic coupling configuration in which the seat portion and the backrest are operated in a predetermined relation. In general, a seat portion of a chair covered with cloth or leather is placed on a seat support member of an office chair. The backrest support member actually extends rearward from the synchro mechanism and supports the backrest of the office chair on a vertical cantilever. The seat support member and the back support member are usually elastically coupled, and for example, the back tilt caused by the chair user leaning on the backrest induces the rear end of the seat downward. It is supposed to do.

このような背凭れの「傾斜抵抗」を変化させるために、シンクロ機構は、通常、同機構に予め負荷を掛けるようにバネ部品が組み入れられている。この予負荷の大きさは、椅子のユーザーの体重による。   In order to change the “tilt resistance” of the backrest, the synchro mechanism is usually provided with a spring component so as to apply a load to the mechanism in advance. The magnitude of this preload depends on the weight of the chair user.

本発明の目的は、背凭れの「傾斜抵抗」を変化させるためのバネ張力の調整が必要とされないシンクロ機構を提供することにある。   An object of the present invention is to provide a synchro mechanism that does not require adjustment of the spring tension for changing the “tilt resistance” of the backrest.

この目的は、請求項1に記載のシンクロ機構によって達成される。このシンクロ機構では、横軸線の周りで回動可能な背凭れ支持部材は、背凭れの後方への傾斜が座部支持部材の後方領域のリフティングを誘導させるように、一方が基部支持体に他方が座部支持部材の背凭れの後端部に回動可能な方法で直接に連結されている。また、座部支持部材の前方領域が、同時にリフティングを引き起こすように、座部支持部材が基部支持体に連結されるシステムを有している。   This object is achieved by the synchronization mechanism according to claim 1. In this synchro mechanism, the backrest support member that can be rotated about the horizontal axis is such that one of the back support members and the other is supported on the base support body so that the rearward inclination of the backrest induces lifting of the rear region of the seat support member. Is directly connected to the rear end of the backrest of the seat support member in a rotatable manner. It also has a system in which the seat support member is coupled to the base support so that the front region of the seat support member simultaneously causes lifting.

本発明の基本的アイディアは、オフィス椅子のユーザーが背凭れにもたれることによって自身を「リフティング」させるということである。公知のバネ張力を調整する制御のように、複雑な制御メカニズム(ウォームギア、ハメバ歯車、ねじ付ロッドなど)を含んでいるものは、必要とされない。これは、シンクロ機構の製造の費用をかなり減少させると共に、信頼性が向上する。   The basic idea of the present invention is that the user of the office chair “lifts” himself by leaning back. What is known to involve complex control mechanisms (worm gears, hameba gears, threaded rods, etc.) is not required, as is the known control of adjusting spring tension. This significantly reduces the cost of manufacturing the synchro mechanism and increases reliability.

座部支持部材は、その後方領域のみでなく、同時に座部支持部材の前方領域でもリフティングが起こるという事実により、背凭れに対し所定の関係で座部の同時上向きと後向きの同期的運動が催される。設計の選択により、背凭れの開き角は、公知の解決手段と比較すると、かなり広くすることができる。これは、極端な後方位置も同様に可能である。   Due to the fact that the seat support member is lifted not only in the rear region but also in the front region of the seat support member at the same time, the seat portion is synchronously moved upward and backward in a predetermined relationship with the backrest. It is. Depending on the design choice, the opening angle of the backrest can be made considerably wider compared to known solutions. This is possible for extreme rear positions as well.

有利な本発明の実施形態は、従属クレームにおいて与えられる。   Advantageous embodiments of the invention are given in the dependent claims.

特有の効果を有するものは、基部支持体が直線状ガイドを介して座部支持部材の前端部に連結される構成である。これは、背凭れと共に座部の同期された直線運動を容易にすることになる。直線ガイドトラックを有する直線状ガイドのほかに、複数の異なるガイドトラックも、もちろん可能である。前記ガイドの形状、ガイドの位置(例えば、水平物に関するガイドの傾斜角)などは、座部支持部材の同期運動の個々の適用を容易にする。例えば、全く如何なる「傾斜」もなく、絶対的に直状仕様で座部支持部材が背凭れと同期して動くことは可能である。ガイドの適切な設計では、わずかに「傾斜」させるも可能である。他の変形例は、基部支持体と座部支持部材との間の連結ポイントを、座部の前端部からの距離が、より小さくあるいはより大きくなるように配置することにより達成できる。   What has a peculiar effect is a structure by which a base support body is connected with the front-end part of a seat part support member via a linear guide. This will facilitate synchronized linear motion of the seat with backrest. In addition to a linear guide with a linear guide track, a plurality of different guide tracks are of course possible. The shape of the guide, the position of the guide (e.g., the tilt angle of the guide with respect to a horizontal object), etc. facilitates the individual application of the synchronous movement of the seat support member. For example, it is possible for the seat support member to move in synchronism with the backrest with absolutely straight specifications without any “tilt”. With proper design of the guide, it can be slightly “tilted”. Another modification can be achieved by arranging the connection point between the base support and the seat support member such that the distance from the front end of the seat is smaller or larger.

オフィス椅子が、所定の設計がなされた座部領域を有するとき、つまり、ユーザーが更に後方位置へ背凭れを任意に傾動するように設計された座部領域を有するとき、いわゆる「シャツ剥れ現象」が非常に効果的に阻止できる。   When the office chair has a seat area with a predetermined design, i.e. when the user has a seat area designed to tilt the backrest further to the rear position, the so-called "shirt peeling phenomenon" Can be blocked very effectively.

本発明の「自己調整」機構として要求される形態のレバーは、背凭れ支持部材と基部支持体との間を連結する旋回軸線(椅子の長手方向に見られる)が、背凭れ支持部材と座部支持部材との間を連結するヒンジ軸線の後方に位置されているという構成により、好ましく達成される。   The lever of the form required as the “self-adjusting” mechanism of the present invention has a pivot axis (seen in the longitudinal direction of the chair) that connects between the back support member and the base support, and the back support member and the seat. This is preferably achieved by the configuration of being positioned behind the hinge axis connecting the part support members.

本発明によれば、バネ張力の調整は必要とされないが、作動領域を調整するデバイスを設けることもできる。これは、座部支持部材に本質的に水平にバネ部材を配置するという効果的な方法によって好ましく達成されるが、このバネ部材は、一方が座部支持部材に連結され、他方が、基部支持体に設けられかつ基部支持体を横断するように配置された軸受軸に連結されている。軸受軸は、その回転によって偏心する設計であり、ユーザーは、軸受軸のセンターとバネサスペンションを変位させ、バネ張力を「ハード」と「ソフト」の間で少なくとも2つのセッティング調整を容易にする。   According to the present invention, adjustment of the spring tension is not required, but a device for adjusting the operating region can also be provided. This is preferably accomplished by the effective method of placing the spring member essentially horizontally on the seat support member, one of which is connected to the seat support member and the other is the base support. It is connected to a bearing shaft provided on the body and arranged to cross the base support. The bearing shaft is designed to be eccentric due to its rotation, and the user displaces the center of the bearing shaft and the spring suspension to facilitate adjusting the spring tension between “hard” and “soft” at least two settings.

本発明は、従来から公知の解決手段と比較して、建設的で非常に簡素な旋回機構となっている。これは、製造の費用を低減する。さらに、その単純な構成にもかかわらず、いわゆる「シャツ剥れ現象」を低減させる。換言すれば、複雑化やコストの増大方向に向かうことなく、非常に高い着座快適性が達成される。   The present invention is a constructive and very simple turning mechanism as compared with the conventionally known solutions. This reduces manufacturing costs. Furthermore, despite the simple configuration, the so-called “shirt peeling phenomenon” is reduced. In other words, a very high seating comfort can be achieved without going in the direction of increasing complexity and cost.

本発明の1つの実施形態を、図面につき詳細に説明する。   One embodiment of the invention will now be described in detail with reference to the drawings.

図1において、シンクロ機構は、テーパソケット2によって椅子柱(図示せず)の頂端部に設けられている基部支持体1に特徴がある。シンクロ機構は、本質的にフレーム形の座部支持部材3(図3参照)と、平面的にフォーク形の背凭れ支持部材4と、基部支持体1の両側に設けられた側板部5、6とを有している。全ての図面において、基本的な位置は、背凭れ支持部材4が本質的に垂直の位置にある。   In FIG. 1, the synchro mechanism is characterized by a base support body 1 provided at a top end portion of a chair column (not shown) by a taper socket 2. The synchro mechanism includes an essentially frame-shaped seat support member 3 (see FIG. 3), a planar fork-shaped backrest support member 4, and side plate portions 5 and 6 provided on both sides of the base support 1. And have. In all the drawings, the basic position is that the back support member 4 is in an essentially vertical position.

表面が布張りされた座部7は、座部支持部材3上に載置され、詳示しない固定部材で通例の方法で組み立てられている。座部7は、座部支持部材3が如何なる運動しても対応するように、座部支持部材3に確実に固定されている。背凭れ(図示せず)は、背凭れ支持部材4に取り付けられており、最近のオフィス椅子では、高さ調節可能である。また、背凭れは、単一ユニットとして背凭れ支持部材4と連結することもできる。   The seat part 7 whose surface is upholstered is placed on the seat part supporting member 3 and is assembled by a usual method with a fixing member not shown in detail. The seat portion 7 is securely fixed to the seat portion support member 3 so as to cope with any movement of the seat portion support member 3. A backrest (not shown) is attached to the backrest support member 4 and is adjustable in height in modern office chairs. The backrest can also be connected to the backrest support member 4 as a single unit.

図から明らかなように、実際の動き関連する限りにおいて、シンクロ機構全体は、中央長手方向平面M(図4参照)に対して鏡面対称に設計されている。したがって、以下の説明は、常に旋回機構の構成部材は対である。   As is apparent from the drawing, the entire synchro mechanism is designed to be mirror-symmetric with respect to the central longitudinal plane M (see FIG. 4) as far as actual movement is concerned. Therefore, in the following description, the components of the turning mechanism are always a pair.

背凭れ支持部材4は、一方が、基部支持体1の自在軸受8に取り付けられ、背凭れ支持部材4が自在軸受8を介して基部支持体1に直接にヒンジ連結されている。この結果、実際には背凭れを有する背凭れ支持部材4は、自在軸受8を挿通する旋回軸線9の周りで、傾斜方向S(図2参照)に傾斜可能となる。自在軸受8は、側板部5、6の前端部10の前に設けられている。   One of the backrest support members 4 is attached to the universal bearing 8 of the base support 1, and the backrest support member 4 is directly hingedly connected to the base support 1 via the universal bearing 8. As a result, the backrest supporting member 4 having the backrest can be inclined in the inclination direction S (see FIG. 2) around the turning axis 9 through which the universal bearing 8 is inserted. The universal bearing 8 is provided in front of the front end portions 10 of the side plate portions 5 and 6.

他方、背凭れ支持部材4は、その側板部5、6の前端部10が座部支持部材3の後端部12とヒンジ11を介して連結されている。このようにすれば、背凭れが後傾する結果、座部支持部材3は、傾斜方向Sに移動され、側板部5、6によって形成されたレバー構成によりリフティングされる。換言すれば、揺動がヒンジ11の軸線13の周りで起こる。   On the other hand, the back support member 4 has the front end portions 10 of the side plate portions 5 and 6 connected to the rear end portion 12 of the seat support member 3 via a hinge 11. In this way, as a result of the backrest tilting backward, the seat support member 3 is moved in the tilting direction S and lifted by the lever configuration formed by the side plates 5 and 6. In other words, the swinging occurs around the axis 13 of the hinge 11.

椅子の長手方向14で見れば、基部支持体1と背凭れ支持部材4との連結部分での旋回軸線9は、座部支持部材3と背凭れ支持部材4との連結部分でのヒンジ軸線13の後方に設けられることになる。さらに、座部支持部材3と背凭れ支持部材4との連結部分でのヒンジ軸線13は、基部支持体1と背凭れ支持部材4との連結部分での旋回軸線9の位置より上にある。   When viewed in the longitudinal direction 14 of the chair, the pivot axis 9 at the connection portion between the base support 1 and the back support member 4 is the hinge axis 13 at the connection portion between the seat support member 3 and the back support member 4. It will be provided behind. Further, the hinge axis 13 at the connection portion between the seat support member 3 and the backrest support member 4 is above the position of the pivot axis 9 at the connection portion between the base support 1 and the backrest support member 4.

基部支持体1は、座部支持部材の前端部15の方向に向って伸びる2つの袖部16、17を有している。図3から明らかなように、袖部16,17は、座部支持部材3の前方領域の直線状のスライドガイド18に各々案内され、軸受軸19に連結されている。   The base support 1 has two sleeve portions 16 and 17 extending toward the front end portion 15 of the seat support member. As is clear from FIG. 3, the sleeve portions 16 and 17 are each guided by a linear slide guide 18 in the front region of the seat support member 3 and are connected to a bearing shaft 19.

この構成により、圧力が後方下方の傾斜方向Sとなるように背凭れと背凭れ支持部材4に掛かるとき、リフティングH1を体験するのは、座部支持部材3の後領域だけではない(図2参照)。座部支持部材3の前領域も、同期様式で持ち上げられる(リフティングH2)。換言すれば、座部領域の前方と後方の両方が同時にリフティングする。座部7は、全体的にリフティングされる。   With this configuration, it is not only the rear region of the seat support member 3 that experiences the lifting H1 when the pressure is applied to the backrest and the back support member 4 so that the pressure is in the rearward downward inclination direction S (FIG. 2). reference). The front region of the seat support member 3 is also lifted in a synchronous manner (lifting H2). In other words, both the front and rear of the seat area are lifted simultaneously. The seat 7 is lifted as a whole.

座部表面のパッド(覆い)20は、成形発泡体でできている(特に図2参照)。パッドは、座部の長手方向14で互いに配置される2つの異なる座部領域21、22に分割され、かつそれらの覆いも異なっている。本実施形態で使用される座面の構成としては、座部前領域21(覆い20のトータル長さの約30%〜40%)は、覆いの厚さが「スタンダード」であり、座部後領域22(トータル長さの70%と60%間)は、後方に沈むユーザーを戻す(rolling back)という目的で調節可能な覆い(variable upholstery)が設けられている。本実施形態では、座部後領域22の覆いの厚さは、座部前領域21の覆いの厚さと比較して、少なくとも20mmより高くしている。座部前領域21から座部後領域22への移行部の状態は、非常にソフトで如何なる隆起線もない滑らかであることが好ましい。特に、良好な結果は、細長い平らなS字形の移行領域とすれば達成される。座部前領域21から座部後領域22への移行部は、主にユーザーの体重を座部前領域21にかかるようなノーマルな(「標準的な」)位置に配置されている。圧力が背凭れに掛かるとき、ユーザーの骨盤は、水平なS字形上で座部後領域22に向って転動する。このようにユーザーは、後方下方への背凭れの移動に追従する。換言すれば、ユーザーの後方移動とそれに関連する後領域の座部7への圧力は、座部を「曲がり」やすくすると共に、ローリングの形式でユーザーによって覆い20に滑りを生じさせる。背凭れとユーザーとの間の非常に同期した連続的な動きは、このような方法で達成される。この結果、いわゆる「シャツ剥れ現象」をかなり減らすことができる。   The pad (cover) 20 on the seat surface is made of a molded foam (particularly see FIG. 2). The pad is divided into two different seat regions 21, 22 which are arranged with respect to each other in the longitudinal direction 14 of the seat and their coverings are also different. As a configuration of the seating surface used in the present embodiment, the seat front area 21 (about 30% to 40% of the total length of the cover 20) has a cover thickness of “standard”, and the rear seat part. Region 22 (between 70% and 60% of the total length) is provided with a variable upholstery for the purpose of rolling back the user sinking backwards. In the present embodiment, the thickness of the cover of the seat rear region 22 is at least 20 mm higher than the thickness of the cover of the seat front region 21. The state of the transition from the seat front region 21 to the seat rear region 22 is preferably very soft and smooth without any ridges. In particular, good results are achieved with an elongated flat S-shaped transition region. The transition from the seat front region 21 to the seat rear region 22 is arranged at a normal (“standard”) position where the weight of the user is mainly applied to the seat front region 21. When pressure is applied to the backrest, the user's pelvis rolls toward the rear seat area 22 on a horizontal S-shape. In this way, the user follows the movement of the backrest downward and downward. In other words, the backward movement of the user and the associated pressure on the seat 7 in the rear region makes the seat easy to “bend” and cause the cover 20 to slip by the user in the form of rolling. A very synchronized and continuous movement between the backrest and the user is achieved in this way. As a result, the so-called “shirt peeling phenomenon” can be considerably reduced.

発泡体は、後方に伸びることができるように、後部座面端部23の方向に自由であることが好ましい。   The foam is preferably free in the direction of the rear seat surface edge 23 so that it can extend rearward.

「覆い」のコンセプトは、使用する材料に関係なく、いかなる型式でも柔軟な座面設計とすることを意味するものと理解されるべきである。成形された発泡体のほかに、何か他の弾力ある材料を使うこともできる。例えば、バネパケット(spring packets)のようなものや、シリコンクッションと発泡体を合わせたような材料の組み合わせも使われる。例えば、2つのゾーン発泡体を使用することも、同様に可能である。   The concept of “cover” should be understood to mean a flexible seating design of any type, regardless of the material used. In addition to the molded foam, some other resilient material can be used. For example, a combination of materials such as spring packets or a combination of silicone cushion and foam is also used. For example, it is equally possible to use two zone foams.

本実施形態で示された背凭れの「傾斜抵抗」の固さは、「ハード」から「ソフト」の2段階の間で切り換えることができる。このために、引張バネ24は、座部支持部材3に本質的に水平に設けられ、その前端部25は偏心した軸受軸19に、その後端部26は座部支持部材3に取り付けられている。軸受軸19は、側部に設けられた作動部材27によって第1の位置から第2の位置に、軸線の周りで回動できる(図4参照)。軸受軸19(図4参照)の偏心の設計により、引張バネ24の前方取り付け位置は、軸受軸19が回動するとき、同様に変化する。したがって、引張バネ24は、当初の応力が変化することになる。これにより多少固い傾斜抵抗が、軸受軸19の位置と関連して達成される。引張バネ24の数は、1つに限定されるものではない。設計によっては、更なる引張バネ24を、平行に設けることもできる。   The stiffness of the “tilting resistance” of the backrest shown in the present embodiment can be switched between two stages of “hard” to “soft”. For this purpose, the tension spring 24 is provided essentially horizontally on the seat support member 3, its front end 25 is attached to the eccentric bearing shaft 19 and its rear end 26 is attached to the seat support member 3. . The bearing shaft 19 can be rotated around the axis line from the first position to the second position by an operating member 27 provided on the side (see FIG. 4). Due to the eccentric design of the bearing shaft 19 (see FIG. 4), the front mounting position of the tension spring 24 changes similarly when the bearing shaft 19 rotates. Therefore, the initial stress of the tension spring 24 changes. Thereby, a somewhat stiff tilt resistance is achieved in relation to the position of the bearing shaft 19. The number of tension springs 24 is not limited to one. Depending on the design, further tension springs 24 can be provided in parallel.

背凭れの傾斜を抑えることは、提示した機構から明らかであるが、作動レバー28によってどのように動作されるかについては、ここでは詳述を省略する。   Although it is clear from the presented mechanism that the inclination of the backrest is suppressed, the details of how it is operated by the operation lever 28 will be omitted here.

本発明は、構成が簡素化した、椅子の座部と背凭れ部を相関動作させるシンクロ機構を提供できる。   INDUSTRIAL APPLICABILITY The present invention can provide a synchro mechanism that has a simplified configuration and performs a correlation operation between a seat portion and a backrest portion of a chair.
